| * [ARM] Fix /proc/cpuinfo format for ARM SMPRussell King2005-11-06
| | | | | | | | | | | | | | | | glibc expects to count lines beginning with "processor" to determine the number of processors, not lines beginning with "Processor". So, give glibc the format it expects. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] Don't call dump_cpu_info unless we're bootingRussell King2005-11-06
| | | | | | | | | | | | | | | | We don't want to call dump_cpu_info() from cpu_init() after boot since it produces a lot of unnecessary noise - since cpu_init() gets called on resume and hotplug cpu insertion events. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| * [ARM] 3113/1: PXA: Allow machines to override (and also reuse) pxa pm functionsRichard Purdie2005-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Richard Purdie Update the PXA pm.c file to allow machines (such as the Sharp Zaurus) to override the standard pm functions but reuse/wrap them where needed. The init call is made slightly earlier to give machine code an init level to override them in removing any race.

| * [ARM] 3089/1: ixp4xx AHB/PCI endianness fixAlessandro Zummo2005-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Alessandro Zummo This patch fixes AHB/PCI endianness problems when the processor is in little-endian mode. The patch configures the CSR register closely following the directives in [1], paragraph 4.1, page 19. According to the considerations in [1], page 11, while the AHB bus supports both endian modes, on the IXP4XX it always uses big-endian. The PCI bus is connected to the South AHB. A wrong setting in the CSR register will thus cause a malfunctional PCI bus. A schematic diagram of the bus interconnections on the IXP4XX can be found in [1], page 18. The patch has been verified to work on the NSLU2 in both LE and BE modes. The author is Peter Korsgaard.

* | [PATCH] ppc64: support 64k pagesBenjamin Herrenschmidt2005-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a new CONFIG_PPC_64K_PAGES which, when enabled, changes the kernel base page size to 64K. The resulting kernel still boots on any hardware. On current machines with 4K pages support only, the kernel will maintain 16 "subpages" for each 64K page transparently. Note that while real 64K capable HW has been tested, the current patch will not enable it yet as such hardware is not released yet, and I'm still verifying with the firmware architects the proper to get the information from the newer hypervisors.

* | [PATCH] reset tss->io_bitmap_owner in sys_ioperm()Bart Oldeman2005-11-05
|/ | | | | | | | | | | | | | | my patch "x86: initialise tss->io_bitmap_owner to something" (commit ID d5cd4aadd3d220afac8e3e6d922e333592551f7d) introduced a problem with a program (DOSEMU) that called ioperm after already doing some port i/o. The problem is that a process switch return causes tss->io_bitmap_base to be set to IO_BITMAP_OFFSET so that the fault (that *really* sets the io bitmap) never triggers. This fixes that regression.

| * powerpc: Fix vmlinux.lds.S for 32-bitPaul Mackerras2005-11-04
| | | | | | | | | | | | | | | | | | | | | | | | We can't currently use asm-ppc/page.h in vmlinux.lds.S, so until we have a merged page.h, define PAGE_SIZE and KERNELBASE locally. Also gets rid of some dynamic executable cruft that we had for 32-bit. With -Ttext=$(KERNELBASE) this didn't cause any problem, but when we changed to putting . = KERNELBASE in the vmlinux.lds.S this cruft caused the text to get linked at 0xa0 instead of 0xc0000000. Oops. Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no reason for smp_release_cpus() to be asm, and most people can make more sense of C code.

| | * | powerpc: Cleanup vpa codeMichael Ellerman2005-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | register_vpa() doesn't actually do a VPA register call it just uses the flags you pass it, so rename it to vpa_call() to be clearer. We can then define register_vpa() and unregister_vpa() which are both simple wrappers around vpa_call(). (we'll need unregister_vpa() for kexec soon) We can then cleanup vpa_init(), and because vpa_init() is only called from platforms/pseries we remove the definition in asm-ppc64/smp.h.

| | * | powerpc: Set entry point and text address in linker scriptMichael Ellerman2005-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we set the kernel entry point and the address of the text section in the Makefile, using CONFIG_KERNEL_START. But we've already got <asm/page.h> in the linker script, so we can just use KERNELBASE directly. That means if we ever change KERNELBASE there's one less place to change it. And we can set the entry point with ENTRY(). There are zero differences from "readelf -a vmlinux" with or without this patch. Signed-off-by: Michael Ellerman <michael@ellerman.id.au>

The only thing that's really changed is that we now allocate crash_notes properly on PPC32. It's address is exported via sysfs, so it's not correct for it to be a pointer. I've also removed some of the "we don't use this" comments, because they're wrong (or perhaps were referring only to arch code). Signed-off-by: Michael Ellerman <michael@ellerman.id.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These days, the NACA only exists on iSeries. Therefore, this patch moves naca.h from include/asm-ppc64 to arch/powerpc/platforms/iseries. There was one file including naca.h outside of platforms/iseries - arch/ppc64/kernel/udbg_scc.c. However, that's obviously a hangover from older days. The include is not necessary, so this patch simply removes it. Built and booted on iSeries, built for G5 (which uses udbg_scc.o).
